  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  FIG. 1 is a functional block diagram schematically showing an electronic apparatus according to an embodiment of the present invention.

  Hereinafter, an electronic apparatus according to the present invention will be described assuming a portable device such as a smartphone. However, the present invention is not limited to portable devices such as smartphones. The present invention can be applied not only to various electronic devices such as mobile phones, tablet PCs, and notebook computers, but also to electronic devices that are not necessarily carried.

  As shown in FIG. 1, the electronic device 1 includes a main control unit 12, a sub control unit 14, a storage unit 20, a contact detection unit 30, a display unit 40, and an acceleration detection unit 50. As shown in FIG. 1, the electronic device 1 can also include an environmental state detection unit 60.

  The main control unit 12 controls the electronic device 1. The main control unit 12 can be constituted by a processor, for example. In the activated state, the main control unit 12 controls and manages the entire electronic device 1 including the sub control unit 14, the contact detection unit 30, the display unit 40, and the acceleration detection unit 50. Even if the main control unit 12 is activated, the sub control unit 14 may perform part of the overall control and management of the electronic device 1 independently of the main control unit 12. In the present embodiment, the main control unit 12 mainly controls contact detection by the contact detection unit 30 and image display by the display unit 40.

  The sub control unit 14 partially controls the functional units that constitute the electronic device 1. The sub-control unit 14 can be configured by a coprocessor, for example. The sub control unit 14 mainly controls the detection of acceleration by the acceleration detection unit 50. The sub-control unit 14 may control the detection of the status of the surrounding environment by the environmental status detection unit 60 described later. The sub-control unit 14 can also perform these controls based on the control from the main control unit 12.

  In FIG. 1, the main control unit 12 and the sub control unit 14 are illustrated as independent members, but a configuration in which both processes are performed by one control unit may be employed. In the following description, the main control unit 12 and the sub control unit 14 are collectively referred to simply as “control units (12, 14)” as appropriate.

  The storage unit 20 can be configured by, for example, a NAND flash memory. The storage unit 20 can store various types of information as well as various types of application software (hereinafter simply referred to as “applications”) executed in the electronic device 1. In particular, in the present embodiment, the storage unit 20 can store information such as progress or result of processing performed by the main control unit 12 and the sub control unit 14. In the present embodiment, the storage unit 20 can also store information such as results detected by various detection units under the control of the main control unit 12 and the sub control unit 14.

  The contact detection unit 30 detects contact by a user's finger or stylus, and can be configured by a member such as a touch sensor or a touch panel, for example. When the contact detection unit 30 is configured by a touch sensor or a touch panel, various types such as a resistance film method, a capacitance method, and an optical method can be employed. The contact detection unit 30 detects contact in the contact detection unit 30 under the control of the main control unit 12. The contact detection unit 30 outputs a detection signal to the main control unit 12 by detecting contact. The main control unit 12 can recognize the position where the contact is detected in the contact detection unit 30 based on the detection signal. Note that the contact detection unit 30 may detect contact under the control of the sub-control unit 14.

  In the present embodiment, the contact detection unit 30 can record a contact detected while being activated and supplied with power from the main control unit 12 as a contact history even after the contact is no longer detected. Thus, the contact history recorded by the contact detection unit 30 can be deleted by the control of the main control unit 12. Furthermore, when power is not supplied from the main control unit 12, the contact detection unit 30 cannot hold the record, and the recorded contact history is deleted.

  The display unit 40 can be configured by a display device such as a liquid crystal display (LCD), an organic EL display, or an inorganic EL display. The display unit 40 is disposed on the back side of the contact detection unit 30 that normally transmits light. By disposing the display unit 40 on the back side of the contact detection unit 30, contact with an object or the like displayed as an image on the display unit 40 is detected at a corresponding position on the contact detection unit 30. The display unit 20 can display various images such as characters and graphics. In addition, the display unit 20 can display an object such as a push button switch (push button switch) such as a key as an image. This object is an image that suggests to the user an area to be contacted in the contact detection unit 30. When the display unit 40 is an LCD, when displaying an image, the display unit 40 can be illuminated with a backlight or the like to make the display easier to see. In this case, the main control unit 12 can control the lighting of the backlight in conjunction with the activation state of the display unit 40, or can individually control the lighting of the backlight.

  The acceleration detection unit 50 detects acceleration, and can be configured by using an inertial sensor such as a capacitance detection type acceleration sensor, for example. Such an acceleration sensor can also detect the gravity applied to the sensor, and can determine the inclination of the acceleration sensor by performing appropriate processing on the detected signal. Such an acceleration sensor can also detect the movement of the sensor, and can obtain information such as an applied shock and vibration by performing an appropriate process on the detected signal. Therefore, by installing the acceleration detection unit 50 inside the main body of the electronic device 1 and the like, information such as the tilt (with respect to the vertical direction) of the electronic device 1 and the impact and vibration applied to the electronic device 1 is obtained. be able to.

  The acceleration detection unit 50 detects the acceleration applied to the electronic device 1 under the control of at least one of the main control unit 12 and the sub control unit 14. The acceleration detection unit 50 outputs a detection signal to at least one of the main control unit 12 and the sub control unit 14 by detecting acceleration. The main control unit 12 and the sub control unit 14 can recognize the acceleration applied to the electronic device 1 based on the detection signal.

  The environmental condition detection unit 60 includes an atmospheric pressure sensor that detects ambient atmospheric pressure, a UV sensor that detects ambient ultraviolet light, a proximity sensor that detects proximity to an object present in the surroundings, a humidity sensor that detects ambient humidity, and a temperature. Various devices such as a temperature sensor to be detected can be used. In addition, the environmental condition detection unit 60 may be a CCD image sensor, a GPS signal receiver, or the like, and may be any detection means as long as it contributes to the detection of the environment surrounding the electronic device 1. be able to. The sub control unit 14 and the main control unit 12 can recognize the status of the surrounding environment in which the electronic device 1 is placed, according to the installed environmental status detection unit 60.

  The main control unit 12 can shift the electronic device 1 to the sleep mode or the suspend mode, for example, when an operation input by the user is not detected. Here, in the present embodiment, the sleep mode includes a state in which a part of the functions of the electronic device 1 is restricted, for example, a state where no screen is displayed on the display unit 40. Note that the sleep mode includes a state where the screen is drawn on the LCD but the backlight is turned off when the display unit 40 is configured by the LCD. In the present embodiment, in the suspend mode, for example, a state in which the contact detection unit 30 has not detected contact, a state in which the main control unit 12 is suspended, or the main control unit 12 is not activated and an activation instruction is issued. A state in which some of the functions of the electronic device 1 are restricted, such as a waiting state, is included. The main control unit 12 can reduce the power consumption by shifting the electronic device 1 to the sleep mode or the suspend mode as compared with a state where the electronic device 1 is normally activated. In such a sleep mode and suspend mode, part or all of the operations performed by the main control unit 12 are usually restricted.

  Next, the operation of the electronic device 1 according to this embodiment will be described. 2 to 4 are diagrams for explaining operations of main elements constituting the electronic device 1.

  FIG. 2 shows a state in which the electronic device 1 that has been in the suspend mode cancels the suspend mode of the electronic device 1 and displays a screen on the display unit 40 by detecting the continuous operation of the tap operation and the touch operation by the user. It is a figure explaining. In the present embodiment, “continuous operation” means that the second operation is performed within a predetermined time from the first operation. Here, it is preferable that the predetermined time is within a relatively short time.

  In the present embodiment, when the electronic device 1 detects a user's continuous operation on the contact detection unit 30, for example, the electronic device 1 cancels the suspend mode and makes the electronic device 1 usable. In the present embodiment, “putting the electronic device 1 into an available state” specifically means that the display unit 40 starts displaying an image. This is because the user can perform the following operation on the electronic device 1 by visually recognizing the display.

  In this embodiment, when detecting the continuous operation by the user, the first tap (first tap) is detected by the acceleration detection unit 50, but the subsequent second touch (second touch) is contact detection. Detected by the unit 30.

  By detecting the continuous operation in this manner, the main control unit 12 of the electronic device 1 in the initial suspend mode can be prevented from being activated until the first tap is detected. The contact detection unit 30 controlled by the main control unit 12 can also be prevented from being activated until the first tap. For this reason, the electronic device 1 which concerns on this embodiment can reduce power consumption remarkably compared with the case where the main control part 12 and the contact detection part 30 are always started.

  When a continuous operation is detected only by the acceleration detection unit 50, such vibration is continuously generated when the electronic device 1 is moving in a state where it is placed in a bag, for example, when a small vibration is given. There is a risk of erroneous detection as an operation. However, in the present embodiment, the second touch is detected by the contact detection unit 30 as described above. If the user does not actually touch the contact detection unit 30 at the time of the second touch, the display unit 40 does not start displaying an image. Therefore, in the present embodiment, even if the electronic device 1 is vibrated little by little as described above, it is not erroneously detected as a continuous operation. For this reason, in the electronic apparatus 1, power consumption is not wasted by displaying the screen on the display unit 40 unnecessarily.

  In the electronic apparatus 1 according to the present embodiment, the acceleration detection unit 50 always detects acceleration. For this reason, when the electronic device 1 detects continuous operation, it is necessary to activate the sub-control unit 14 that controls the acceleration detection unit 50 so that the acceleration detection unit 50 can detect acceleration. There is.

  As shown in FIG. 2, when the electronic device 1 detects the continuous operation according to the present embodiment, first, the sub control unit 14 activates the acceleration detection unit 50 (ON (1)). As a result, the electronic device 1 is ready to detect the first tap.

  Thus, after the acceleration detection part 50 starts, suppose that the user performed the 1st tap by contacting the contact detection part 30, for example. This timing is referred to as a first tap (α) in FIG. When the acceleration is detected, the acceleration detection unit 50 transmits the acceleration to the sub-control unit 14 (acceleration (2)).

  Here, as described above, since the first tap is detected by the acceleration detection unit 50, the user does not necessarily need to touch the contact detection unit 30, and any mode that gives acceleration to the acceleration detection unit 50. You can tap with. That is, the user can perform the first tap at an arbitrary location on the electronic device 1. The user can also perform a first tap on a desk near the electronic device 1 in a state where the electronic device 1 is placed on a desk, for example. Thus, even if a tap is performed on a desk near the electronic device 1, the impact of the tap is transmitted to the electronic device 1 placed on the desk, and the acceleration detection unit 50 can detect acceleration. Because it can.

  When the acceleration detected by the acceleration detection unit 50 is received, the sub-control unit 14 determines whether or not the received acceleration is a predetermined acceleration caused by the first tap. When the received acceleration is a predetermined acceleration caused by the first tap, the sub control unit 14 activates the main control unit 12 (ON (3)). That is, the sub-control unit 14 does not activate the main control unit 12 regardless of the acceleration detected by the acceleration detection unit 50, but is characteristic when the acceleration detection unit 50 performs the first tap. The main control unit 12 is activated only when an acceleration pattern is detected. For this reason, the sub-control unit 12 needs to grasp a characteristic acceleration pattern (for example, an acceleration change pattern, etc.) generated when the first tap is performed.

  Since various patterns of such acceleration are assumed depending on the situation of the electronic device 1, characteristic acceleration patterns detected in these various situations are prepared in advance. For example, acceleration when the electronic device 1 is tapped with the finger of the other hand while holding the electronic device 1 with one hand, and when the electronic device 1 is tapped while the electronic device 1 is placed on a desk or the like Patterns such as acceleration can be prepared in advance. Such an acceleration pattern may be stored in the sub-control unit 12 or may be read out from the storage unit 20. As a characteristic acceleration pattern generated when a tap is performed, a pattern stored in advance may be used, or a pattern learned by the sub-control unit 14 from a tap performed by a user may be used.

  The characteristic acceleration pattern generated when the first tap is performed is, for example, when the acceleration detection unit 50 can detect the acceleration in each direction of the xyz axis, and the contact detection unit 30 that the user performs a continuous operation. A pattern in which the acceleration in the normal direction of the surface changes sharply can be used.

  In this way, the sub control unit 14 determines whether or not the acceleration detection unit 50 has detected a predetermined acceleration due to the first tap. When it is determined that the acceleration is a predetermined acceleration caused by the first tap, the sub control unit 14 activates the main control unit 12 (ON (3)). When the main control unit 12 is activated, the electronic device 1 shifts from the suspend mode to the sleep mode. It is also assumed that the contact detection unit 30 cannot issue a request to start detection of contact at the moment when the main control unit 12 is activated. Therefore, in the present embodiment, as soon as the main control unit 12 is activated, the contact detection unit 30 is activated (ON (4)). Then, the contact detection unit 30 operates to detect a contact without waiting for the detection start request (5) from the main control unit 12 and leave a history of the contact.

  In FIG. 2, the detection start request (5) is transmitted after some time after the main control unit 12 is activated (ON (3)), and then the detection end request (6) is transmitted. When waiting for the detection start request (5) from the main control unit 12, the contact detection unit 30 can detect only the contact between the detection start request (5) from the main control unit 12 and the detection end request (6). However, in this case, when the time interval from the first tap to the second touch of the user is short, the second touch may not be detected. Therefore, in this embodiment, as described above, the contact detection unit 30 detects a contact without waiting for the detection start request (5) from the main control unit 12, and leaves a history of the contact. Thereby, in this embodiment, the contact detection part 30 can detect the contact from ON (4) from the main control part 12 to a detection end request | requirement (6).

  As described above, in the present embodiment, immediately after the main control unit 12 is activated, the contact history detected by the contact detection unit 30 is recorded. Before the main control unit 12 is activated, the contact detection unit 30 is not activated without being supplied with power from the main control unit 12, and therefore cannot record a contact history or hold a contact history record. . Therefore, in the present embodiment, when the main control unit 12 is not activated when the predetermined acceleration due to the first tap is detected, the contact detection unit 30 deletes the record of the contact history. It is possible to detect contact without any problem. That is, in the present embodiment, the contact detection unit 30 starts from the main control unit 12 when the main control unit 12 is not operating when the acceleration detection unit 50 detects a predetermined acceleration due to the first tap. When a contact detection start request is received, the recorded contact history is maintained.

  In FIG. 2, it is assumed that the second touch (β) by the user is performed between ON (4) and the detection end request (6). Thereby, the contact detection part 30 detects the contact by a 2nd touch between ON (4) and a detection end request | requirement (6). The contact detection unit 30 detects contact due to the second touch between ON (4) and the detection end request (6). The main control unit 12 receives a reply from the contact detection unit 30 that there is a record of contact in the contact history (recorded (7)).

  The main control unit 12 determines whether or not the contact detection unit 30 has detected contact after a predetermined time B from the transmission of the detection end request (6). When no contact is detected during the predetermined time B, the main control unit 12 can determine that the next touch has not been performed following the second touch (β).

  When receiving “recorded (7)” from the contact detection unit 30, the main control unit 12 controls to delete the record of the contact history of the contact detection unit 30 (record deletion (8)). With this control, it is possible to determine whether or not there is a new contact during the predetermined time B. In FIG. 2, during the predetermined time B, the contact detection unit 30 does not detect a new contact. The main control unit 12 receives a reply from the contact detection unit 30 that there is no contact record in the contact history (no recording (9)).

  When receiving a reply from the contact detection unit 30 that there is no contact record, the main control unit 12 performs a second touch within a predetermined time (predetermined time A) from the first tap, that is, a continuous operation. The display unit 40 is activated (ON (10)) and image display is started. That is, in the present embodiment, the sub control unit 14 performs control so that the acceleration detection unit 50 detects a predetermined acceleration caused by the first tap. The main control unit 12 controls the contact detection unit 30 to detect contact by the second touch, and controls the display unit 40 to display an image. The sub-control unit 14 controls the main control unit 12 to be activated if the acceleration detection unit 50 detects a predetermined acceleration caused by the first tap when the main control unit 12 is not operating. When the contact detection unit 30 detects contact by the second touch within a predetermined time after the acceleration detection unit 50 detects the predetermined acceleration caused by the first tap, the main control unit 12 displays the display unit 40. Controls to start displaying an image.

  In the present embodiment, the main control unit 12 controls the contact detection unit 30, but the sub control unit 14 may control the contact detection unit 30. When the sub-control unit 14 controls the contact detection unit 30, after the electronic device 1 detects the second touch, the main control unit 12 can be activated and a screen can be displayed on the display unit 40. In the electronic device 1, power consumption by the main control unit 12 can be further reduced.

  FIG. 3 is a diagram for explaining the operation when the electronic device 1 detects the first tap (α) as in the case of FIG. 2 but does not detect the second touch (β) thereafter. .

  As shown in FIG. 3, after the acceleration detection unit 50 detects a predetermined acceleration caused by the first tap, the contact detection unit 30 detects contact by the second touch for a predetermined time A. Absent. This is because, for example, the user performed the first tap but did not subsequently perform the second touch, or the user did not perform the first tap, but the first tap was performed by some vibration. It is assumed that it is mistakenly detected as an error.

  Also in this case, after transmitting the detection end request (6), the main control unit 12 receives a reply from the contact detection unit 30 that there is no contact recording in the contact history (no recording (9)).

  In FIG. 3, the contact detection unit 30 does not detect contact due to the second touch between ON (4) and the detection end request (6). Therefore, the main control unit 12 receives a reply from the contact detection unit 30 that there is no contact record in the contact history (no recording (9)).

  When receiving a reply from the contact detection unit 30 that there is no record of contact, the main control unit 12 has not performed the second touch within a predetermined time (predetermined time A) from the first tap. The control unit 12 determines that the continuous operation has not been successful, and does not activate the display unit 40 (ON (10)). In this case, the display unit 40 does not start displaying an image.

  When the electronic device 1 has the first tap but does not have the second touch, the electronic device 1 understands that the first tap is erroneously detected. After elapse of a time longer than the predetermined time B, the electronic device 1 suspends the main control unit 12 again and shifts to the suspend mode. The main control unit 12 may turn off the contact detection unit 30 before suspending.

  Thus, according to the electronic device 1 of the present embodiment, even if the acceleration detection unit 50 detects a predetermined acceleration, if the contact detection unit 30 does not detect a contact within a predetermined time, the display is performed. Display of an image on the unit 40 is not started. Therefore, according to the present embodiment, the electronic device 1 is not ready for use unless the user performs a continuous operation. In addition, according to the present embodiment, even when the electronic device 1 detects a predetermined acceleration and erroneously detects that the first tap has been performed, the contact detection unit 30 detects contact by the second touch. Otherwise, the electronic device 1 is not ready for use. Thus, the electronic device 1 according to the present embodiment can be made usable by a simple operation of the user on the touch panel.

  The main control unit 12 stops the power supply to the contact detection unit 30 after receiving the notification of no record (9). Thereby, the contact detection part 30 will be in the OFF state which has not started. In this way, when the contact history information recorded by the contact detection unit 30 is volatile, the history information is not retained.

  FIG. 4 shows a case where the electronic device 1 in FIG. 3 does not detect the second touch (β) during the predetermined time A, but detects the next tap during the subsequent predetermined time B. It is a figure explaining operation | movement.

  The following situations are assumed as situations in which the operations shown in FIGS. 3 to 4 are performed. That is, for example, a case where the user does not perform an operation for a while after performing the first tap and then starts the operation again from the first tap is considered. There is a case where the user performs the continuous operation again, but the electronic device 1 does not recognize it correctly, so that the continuous operation is performed again. It is also conceivable that after the electronic device 1 erroneously detects that the first tap has been performed by detecting a predetermined acceleration, contact by the second touch is not detected, and the user subsequently performs a continuous operation. As another situation in which the operation shown in FIG. 4 is performed, a case where the electronic device 1 is in the sleep mode because the user has not operated the electronic device 1 can be considered.

  The operation shown in FIG. 4 starts before the predetermined time B is completed in FIG. Therefore, in FIG. 4, unlike FIGS. 2 and 3, the acceleration detection unit 50, the main control unit 12, and the contact detection unit 30 are already activated from the start stage shown in FIG. The screen is not displayed. At the start of FIG. 4, the electronic device 1 is in the sleep mode.

  As illustrated in FIG. 4, it is assumed that the user performs the first tap (γ), for example, by contacting the contact detection unit 30 before the predetermined time B continuing from FIG. 3 is completed. When the acceleration due to the first tap is detected, the acceleration detection unit 50 transmits the acceleration to the sub-control unit 14 (acceleration (11)).

  When the acceleration detected by the acceleration detection unit 50 is received, the sub-control unit 14 determines whether or not the received acceleration is a predetermined acceleration caused by the first tap. And when the received acceleration is a predetermined acceleration resulting from the first tap, the sub-control unit 14 notifies the main control unit 12 to that effect (notification (12)). Here, since the main control unit 12 has already been activated, if the acceleration is notified that the acceleration is a predetermined acceleration caused by the first tap, the main control unit 12 immediately requests the contact detection unit 30 to start detection. Can be transmitted (detection start request (13)).

  Here, since the contact detection unit 30 detects the second touch from now on, the main control unit 12 deletes the record of the contact history of the contact detection unit 30 after transmitting the detection start request (13) ( Record erasure (14)). In other words, in the present embodiment, the contact detection unit 30 starts from the main control unit 12 when the main control unit 12 has already been activated when the acceleration detection unit 50 detects the predetermined acceleration due to the first tap. When a contact detection start request is received, the recorded contact history is deleted. In this way, the contact detection unit 30 can always notify the main control unit 12 of the record of the last contact. Here, the reason why such control is performed is that, as described above, while the contact detection unit 30 is activated and power is supplied, a record of contact history is maintained. Therefore, when the contact detection unit 30 originally has a specification that does not hold the record of the contact history, it is not necessary to perform such record deletion (14). In FIG. 4, the main control unit 12 performs the recording deletion (14) after transmitting the detection start request (13) to the contact detection unit 30, but this order may be reversed. You may do it at the same time.

  In FIG. 4, the main control unit 12 sends a detection end request (15) after making a detection start request (13) and a recording erasure (14). Here, the contact detection unit 30 can detect the second touch even when the time interval from the user's first tap (γ) to the second touch (δ) is short. Since the contact detection unit 30 performs the recording deletion (14) after receiving the detection start request (13), the contact detection unit 30 keeps a history of detected contacts until the detection end request (15) is transmitted. Thereby, in this embodiment, the contact detection part 30 can detect the contact between the recording deletion (14) from the main control part 12, and a detection end request | requirement (15).

  In FIG. 2, it is assumed that the second touch (δ) by the user is performed between the recording deletion (14) and the detection end request (15). Thereby, the contact detection part 30 detects the contact by a 2nd touch between a recording deletion (14) and a detection end request | requirement (15). The main control unit 12 receives a reply from the contact detection unit 30 that there is a record of contact in the contact history (recorded (16)).

  The main control unit 12 determines whether or not the contact detection unit 30 has detected contact after a predetermined time B from the transmission of the detection end request (15). When contact is not detected during the predetermined time B, the main control unit 12 can determine that the next touch has not been performed following the second touch (δ).

  When receiving “recorded (16)” from the contact detection unit 30, the main control unit 12 controls to delete the record of the contact history of the contact detection unit 30 (record deletion (17)). With this control, it is possible to determine whether or not there is a new contact during the next predetermined time B. In FIG. 4, during the predetermined time B, the contact detection unit 30 does not detect a new contact. The main control unit 12 receives a reply from the contact detection unit 30 that there is no contact record in the contact history (no recording (18)).

  When receiving a reply from the contact detection unit 30 that there is no contact record, the main control unit 12 performs a second touch within a predetermined time (predetermined time A) from the first tap, that is, a continuous operation. The display unit 40 is activated (ON (19)) and image display is started.

  As described above, according to the electronic apparatus 1 of the present embodiment, even when the display unit 40 is not activated without determining that the first continuous operation has been successful, the display unit 40 is displayed when it is determined that the next continuous operation has been successful. to start. Therefore, according to the present embodiment, the user can reduce the waste of power consumption due to the activation of the display unit 40 due to erroneous detection of the first tap, and even after such determination, By performing the continuous operation, the electronic device 1 can be put into a usable state.

  In the embodiment described above, the first tap is detected by the acceleration detection unit 50, and the second touch is detected by the contact detection unit 30. However, the acceleration detection unit 50 may detect the second touch together with the contact detection unit 30. In other words, when the main control unit 12 detects the predetermined acceleration due to the second touch within a predetermined time after the acceleration detection unit 50 detects the predetermined acceleration due to the first tap, the display unit 40 May be controlled to start displaying an image. The electronic device 1 displays the display unit 40 based on the fact that the acceleration detection unit 50 detects a predetermined acceleration caused by the second touch and the contact detection unit 30 detects the contact by the second touch. It may be activated.

  In the above-described embodiment, the main control unit 12 performs the next touch (β) after the second touch (β) when no contact is detected for a predetermined time B after transmitting the detection end request (6). Judged that it was not done. Here, in FIG. 2, for example, the next (third) touch is further detected within a predetermined time B after the second touch (β) is detected, and the predetermined time is detected after the detection of the third touch. If no contact is detected, it can also be determined that a further (fourth) touch has not been made. As described above, in the present embodiment, the user operation to be detected is not limited to the continuous operation performed twice, but can be an arbitrary number of continuous operations of three times or more.

  In this case, as described above, in the present embodiment, the contact detection unit 30 always records the last contact by controlling whether or not the contact history recorded by the contact detection unit 30 is erased. 12 can be notified. Therefore, the electronic device 1 according to the present embodiment can cause the display unit 40 to display a screen based on the last touch, regardless of how many consecutive touches are detected.

  As described above, in the present embodiment, the operation after the second touch can be detected by the acceleration detection unit 50 together with the contact detection unit 30.

  In this case, after the acceleration detection unit 50 detects the predetermined acceleration due to the first tap, the main control unit 12 further takes into account the detection of the predetermined acceleration due to the second touch. Whether or not the display unit 40 is activated can be determined. Similarly, the operation after the second touch can also be detected by the acceleration detection unit 50. Furthermore, when the acceleration detection unit 50 detects the predetermined acceleration by the tap and does not detect the predetermined acceleration by the tap for a predetermined time, it can be determined that the detected tap is the last touch. Therefore, in this embodiment, the main control unit 12 displays the image when the display unit 40 does not detect the predetermined acceleration for a predetermined time after the acceleration detection unit 50 detects the predetermined acceleration by the second touch. You may control to start.

  In the above-described embodiment, the predetermined time A from when the first tap is detected to when the second touch is detected can be set as appropriate based on a commonly performed continuous operation. Further, it is preferable that the predetermined time A can be appropriately changed later according to the user's preference after being set once. Further, the predetermined time A may be such that the electronic device 1 learns the timing of the continuous operation that is normally performed by the user who is actually operating the electronic device 1. In this case, the user may request the user to perform a continuous operation, and the control unit (12, 14) may learn the timing of the continuous operation based on the continuous operation performed by the user. Further, the control unit (12, 14) may learn the timing of the continuous operation based on the continuous operation normally performed by the user without requiring the user to perform the continuous operation for trial. In other words, the control unit (12, 14) determines a predetermined acceleration based on a predetermined acceleration caused by successive taps detected by the acceleration detection unit 50 or a contact time interval caused by successive touches detected by the contact detection unit 30. Time may be determined. For example, after the display unit 40 starts displaying an image as described above, when an operation for canceling the operation restriction is requested, or when an operation for canceling the operation restriction is received, a screen display is displayed on the display unit 40. By learning the timing of the continuous operation that started the operation, the user can be made to learn without requiring a special operation.

  In the above-described embodiment, the user operation generally performed for the predetermined time B in which it is determined that the next tap or touch is not detected after the main control unit 12 transmits the detection end request to the contact detection unit 30. Can be set as appropriate based on the above. Further, as described above, it is preferable that the predetermined time B is set once and can be appropriately changed later according to the user's preference. In addition, for the predetermined time B, the electronic device 1 may learn the timing of the operation normally performed by the user who is actually operating the electronic device 1.

  Furthermore, in the above-described embodiment, the predetermined time A and the predetermined time B can be set to the same time when detecting the number of taps, or each time depending on the number of taps to be detected. It may be a different time.

  Although the electronic device 1 according to the present embodiment has been described above, the present invention can also be implemented as a method for controlling the electronic device 1 as described above. Furthermore, the present invention can also be implemented as a control program for the electronic device 1 as described above.
